This document provides instructions for removing and installing the flywheel, crankshaft rear seal, and crankshaft wear sleeve on a 3054C engine. The flywheel removal procedure involves installing guide bolts and link bracket to support the flywheel weight before removing all setscrews. For installation, the ring gear may need to be heated to 250°C and aligned correctly. The crankshaft rear seal housing is non-serviceable and must be replaced if removed. A plastic sleeve protects the new seal during installation. The crankshaft wear sleeve is removed using a puller and installed using an oil seal installer, bolt, and washer.
